MACHINE FOR- APPLYING BACKS TO MIRRORS.

Be it known that I, I'IAIL'RY SOLOMON, a citizen of the United States, and resident oi New York city, in the county of New York 5 and State of New York, have invented cer tain new and useful Improvements in Machines tor Applying Backs to Mirrors, of which the following is a' specification.

This invention relates to an improven'ient in a machine or mechanism which automati- (rally applies backs to smallmirrors, such as are carried in the. pocket or in small handbags and the obje ct of this invention is to produce a mechanism of this character which will apply backs made 0t paper,

cloth, leather, or the folding said backs abo like, to said mirrors. ut the marginal edges of the n'iirror and holding the same in posit-ion by means of a folded stiffening member which is applied to t he mirror simultaneously with the application the backing thereto.

Referring to the article shown in Fig. 10: This constitutes a stiffening. member 1 thin malleable metal. which is provided with marginal edge p ortions'i on all of its sides. This stiffening member 1. lies underneath and constitutes a reinforcement for the outer covering 3, which may be made of cloth, leather, paper or any ornau'iental.fabric.

The machine hereinafter described acts to told over the edges 2. on the dotted lines 5 of the stitl'ening member 1 and said folded-over edges 2 hold down similarly folded edge stitiening member is con'ipletely covered by the outer covering 2 and a backing and rein forced edge isprovided completely" around the mirror The completed"mirror is shown in detail in 19. and'13.'

The mechanism for applying the backs to the mirrors isdisclosed in. detail in Figs. 1, 2, and 3 where it will be seen that the same is composed of threemain parts, the same being an upper die portion 6 which cooperates with a lower die 7 to fold down the side edges 20f the stitl'ening member 1 and backing prior to the application of the a) same to the i'nirror. The third main portion of the machine comprlses a central (he pertion 8 which co-operates with the portion 6 an upper plate which is provided with an up ardly extending threaded stud 1O adapted to be received in a plunger 11, forming part of a press which vertically reciprocates the die 6. A set-screw 12 retains the die in its fixed position relative to the portion 11 of the plunger and prevents inadvertent rotation of the die while in use. The plate 9 is provided with a downwardly extending block 13 which has a flat under-surface 14. The block 13 is surrounded by an outer shell 15. the vertical movement of which with respect to the block 13 is limited by means of pins 16 projecting from the ends of the block 13 and entering slots 17 in the ends of the shell 15.

It will be seen therefore that the shell may move vertically with respect to the block 13 within the limits of the slots 17.

At 18 are shown fingers which are piw oted at 19 in cars 20 which project laterally from the ends of the plate 6. These fingers are provided with slots 21 in their inner edges and said slots 21 are adapted to fit over a .:ontinuous wall 22 which extends about the face of the shell 15. Located above the pivots 19 for said fingers 18 are spring-pressed studs 23 which are forced outwardly under the impulse of springs 24. These studs 23 bear against the fingers 18 above their pivots 19, thus normally tending to cause the lower ends of-said fingers to move inwardly so that the slots 21 embrace the wall22 on the shell 15. It will be seen that when such engagement takes place. the shell 15 cannot move vertically and remains in fixed position relative to the block 13.

The lower die 7 is composed of a base 25 from which projects an upwardly extending block 26 surrounded by a frame 27. Said frame 27 is provided with atop portion 28 which projects outwardly and which is normally thrust upwardly by means of springs 29 located at each of its four corners. Studs 3O project upwardly from the base 25 within the springs 29 and serve to act as abutmcnts for the top 28 of the frame 27 when said frame is pressed downwardly by the die 6 as will be hereinafter explained.

The ends of the frame 27 are provided with grooves 31 which form a passage for the fingers 18 on the die 6. The ends ofthe frame27 are provided with slots 32 in which extend pins 33 which project from the ends of the block 26 and limit the upward move nient of the frame 27 under the pressure of the springs 29.

In Fig. 7, the manner in which the dies 6 and 7 co-operate to bend down the side edges 2 of the stiffening member 1 and also the outer covering 3 is shown.

The stiffening member 1 whichhas its side edges slightly downwardly bent as disclosed at 31 in Figure 11, to aid in the bending movementas will be hereinafter explained, is placed upon the block 26 which is then in the position shown in Figs. 3 and el. The covering 3 is placed on top of the stiffening member 1 and the die 6 is caused to descend. Said die 6 descends until its projecting edge 22 contacts with the top 28 on the frame 27 of the die 7. As the frame 15 is held in fixed position by means of-the fingers 18 which are engaging with the edge 22, said frame 15 forces down the frame 27 against the tension of the springs 29 and as such movement continues, the block 26 forces the cover 3 and stiffening member 1 up into the frame 15 and a ainst the underface'lt of the block 13. (bee Fig. 7).

The die 6 is then raised and as it is raised, the stiffening member 1 and cover 3 are rctained within the frame 15 withtheir edges folded downwardly as shown in Fig. 7.

The central die 8 is then placed upon the i die 7 for the application of the covering to the mirror. The die 8 comprises an outer frame 35 on which is supported a top 36. Said top 36 is secured to the frame 35 by means of screws 37 which pass through openings 38 in the frame 35 and thread into said top 36. In order to compensate for mirrors of various thicknesses, resilient inserts'38 are located in recesses in theframe and project upwardly from the frame and space the top 36 from said frame 35. These inserts are made of any resilient material such as blocks of rubber, or if desired coil springs may bemused. As the tops of these inserts 38 project above the upper face of the frame 35, they hold the top 36 at a distance therefrom so that a small space 39 lies between the under side of the top 36 and theupper face of the frame 35. The top 36 is provided with downwardly depending side flanges 40 and 41 which extend completely around the top 36 so that dust, dirt or shreds ofmaterial which accumulate during the operation of the mechanism cannot enter between the parts and 36.

The top 36 is provided with an upper. face 12' which is in the nature of a marginal edge strip extending completely around the top, and a depressed seat 43. The parts 12 and43 are so shaped that they correspond to the under face of the frame 15 on the die 6, so that when said die descends down upon the die 8, the laterally projecting wall 22 on the frame 15 rests upon the marginal edge portion 12 of the top 36, and the under face of the downwardly projecting rim 44 on the frame 15 rests upon the seat 43 (see Fig. 9). At 45 is shown an inclined surface which extends completely around the central opening in the die, and which acts. to bend inwardly the downwardly bent edges of the stiffeningmember 1. The face of said inclined surface 45 is curved or rounded, as disclosed in Figs. 8 and 9 so that it tends to curl" the edges of thestiflening member inwardly as will be hereinafter explained.

Located within the central opening in the die 8 is the mirror-elevating member 46 which is capable of being raised andv lowered within the die, such raising and lowering movement, however, being restricted by means of pins 47 which extend inwardly from. the ends of the frame 354 and enter into slots 48 located in the ends. of the 1nemher as. The member &6 is provided with a downwardly extending side wall 459 and a top piece 50 upon which themirror is placed. The four edges of the top piece 50 are inclined or beveled as at 51, said beveled edge being curved or rounded to form pressing surface which co-operates with the curved edge 45011 the top 36 to bend the edge of'the stiifening member 1 and cover 3 inwardly and about the edges of the mirror.

On each of the ends of the top 36 is a cam which is intended to contact with the fii'igers l8 and shift the same so that have had their edges bent downwardly. The

dies 6 and 7 are then separated, the upper die 6 ascending and carrying thebent stiffen ing member and cover within its frame 15 and against the flat under-face 14 of the block 13.

The die 8 is now placed upon the top portion 28 of the lower die 7 the under side of the frame 35 corresponding in shape to the upper face of the top 28 so that said die 8 rests securely upon the top 28. A mir ror a is placed face downward upon the upper surface of the top piece and the die 6 is then lowered. As the die 6 descends, the fingers 18 come into contact with the cams 52 on the top 36 so that said fingers are spread outwardly and are thus caused to become disengaged from the wall 22 on the frame 15. Thus, when the under side of said frame COJIT"-"'i11lLO contact with the upper face of the top 36 on the die 8, the frame is forced upwardly. As the die 6 continues its descent the frame 27 which surrounds the block 26 is forced downwardly against the tension of the springs 29. The bottom of the wall 49 on the mirror-elevating member 46 comes into contact with the upper face of the block 26 and rests thereon so that as the downward movement of the die 6 continues further, the mirror t is forced against the stiffening member and the edges of the stif fening member. 1 and cover 3 are curled in wardly by the pressure of the inclined curved faces 45 and 51 on the top 36 and mirrorelevating member 46 respectively; Figure 9 shows the parts 111 the act ofbeginnmg this curling or bending of the edges of After the final pressure together of the dies has applied the backing, the die 6' is raised and the completed or backed mirror is removed. a

I haveshown the dies of such, a form as-is required for the backing of a mirror of sub stantially rectangular shape, but it will-be obvious that any shaped mirror may be backed by a mere change in the shape of the dies. i

It will also be seen that by the use of resilient spacers between the parts 35 and 36 I provide an arrangement whereby break age of mirrors by reason of variances in thickness is avoided, for anyexcessive downward pressure upon the bending groove 45 by thelblock 1 3, as the die 6 is descending is taken up bythe resilientspacers 38 before a-ypressure sufficient tobreak the mirror is imposed. upon the mirror.
